Research ArticleOpen accessEvery word in the titleHeavy Metals Content of the Grassland Soil around Katima Mulilo Municipal Solid Wastes Dumpsite, NamibiaJ. Abah, P. Mashebe, S.A. OnjefuThe effects of open wastes dumpsites on the immediate vicinity continue to generate safety concern. This study determined the levels of lead, chromium, cadmium, arsenic, nickel, cobalt, copper and manganese in soil samples collected at two depths: 0-15 and 15-30 cm within and around Katima Mulilo municipal solid wastes dumpsite and a control site. The samples were digested according to … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 18 Mar 2017 · 7,485 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Bioethanol Wastes as an Alternative Phosphorus Source for Snap Bean and Radish ProductionXiaolin Liao, Ben Hogue, Shouliang Zhu et al.Biorefinery waste has potential to provide alternative sources of phosphorus (P) for plant industry if biomass has been pretreated by phosphoric acids during its production process. In this study, we investigated the potential of the fermentation waste from a bioethanol process as a P fertilizer. Three treatments were set up for growing crops of snap bean (var., Bronco) and radish … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 4 Feb 2016 · 8,146 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreliminary Evaluation of the Potential Biogas Production of Food-Processing Industrial WastesC. Roati, S. Fiore, B. Ruffino et al.Problem statement: An Anaerobic Digestion (AD) process, traditionally applied to wastewater and sewage sludge treatment, has a great potential in the valorization of food-processing industry wastes. Approach: This study is focused on the evaluation of the theoretical biogas and methane production of some food wastes, coming out from rice, hazelnut and wine processing, on the grounds of their physical-chemical characterization. … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 6 Jun 2012 · 7,985 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePalm Oil Milling Wastes and Sustainable DevelopmentA.C. Er, Abd. Rahim Md. Nor, Katiman RostamProblem statement: Palm oil milling generates solid wastes, effluent and gaseous emissions. The aim of this study is to assess the progress made in waste management by the Malaysian palm oil milling sector towards the path of sustainable development. Sustainable development is defined as the utilization of renewable resources in harmony with ecological systems. Inclusive in this definition is the … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,697 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBehaviour of Main Microbiological Parameters And of Enteric Microorganisms During the Composting of Municipal Solid Wastes and Sewage Sludge in A Semi-Industrial Composting PlantOlfa Fourti, Naceur Jedidi, Abdenaceur HassenThis study was focused on the microbiological aspects of composting and on the behaviour of main prevalent microbial communities (non-pathogenic and selected pathogenic bacteria) during the composting process of municipal solid wastes and sewage sludge in a semi-industrial composting plant. Results showed that the dehydrogenase activity and Biomass C / Biomass N ratio showed a noticeable increase in the two … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 7,313 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBIOGAS PRODUCTION FROM TOFU LIQUID WASTE ON TREATED AGRICULTURAL WASTESBudy Rahmat, Tedi Hartoyo, Yaya SunaryaThe Tofu Liquid Waste (TLW) as a pollution might be processed into biogas which was environmentally friendly and had potential to replace burning wood or oil. However, the waste could not directly be employed as the biogas substrate due to the high nitrogen content which was not suitable to the methanogen microorganism on the biogas digester and did not produce … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 1 Feb 2014 · 7,958 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtilization of Soft Wood Wastes as a Feed Stock to Produce Fuel EthanolAdnan M. Khalil, Ali F. Al-Shawabkeh, Ayman S. Mazahreh et al.Problem statement: The current research investigated the utilization of soft wood waste as a feedstock to produce a value-added product-fuel ethanol. Approach: The main issue in converting soft wood waste to fuel ethanol is the accessibility of the polysaccharides for breaking down into monosaccharides. This study focused on the use of steam as the pretreatment method. The governing factors for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,632 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Utilization of Peat, Lignite and Industrial Wastes in the Production of Mineral-Organic FertilizersKrystyna Hoffmann, Józef HoffmannThe results of chemical analyses of the composition of peat, lignite, turkey droppings and the potato industry effluent are presented. The results indicate that the substances can be used in mineral-organic fertilizer recipes. Although lignite and peat do not contain assimilable nutrients, from the ecology and pedology point of view they are valuable components of mineral-organic fertilizers. In order to … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,483 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtilization of Banana, Pineapple and Watermelon Wastes-Substrate: As Consortiums to Remediating Cyanide Polluted SoilFlorence Obiageli Nduka, Samuel Chibuike Ubani, Victor Eshu Okpashi et al.The act of processing cassava for varied food products has come with unguided and wide-spread contamination of cyanide in the environment. The need for effective reduction in cost to enable remediation of cyanide-contaminated sites from cassava mill factories is the purpose of this investigation. This involves bio-stimulation of organic wastes with indigenous microorganisms to degrade cyanide. The application of organic … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 30 Apr 2018 · 9,934 accessesView PDFCite
